SuSE Linux 6.1

Hailing from Nuremberg, Germany, SuSE Linux 6.1 is SuSE's latest release (SuSE Linux 6.2 will be available by the time you read this) featuring the new 2.2 kernel, custom SuSE software, commercial packages (Netscape, StarOffice with personal license, Applixware Office, Corel WordPerfect 8.0 and many others), five CD-ROMs' (and a disk's) worth of software, a 440-page manual and a green chameleon sticker. This is a serious, high-performance distribution which is more complete than practically any single distribution, and at the same time is clean and fast due to effective configuration and intelligent design. Much attention has been paid to the details in this release (as in past releases), and the production gains a lot from SuSE custom software and configuration. Although SuSE is the top Linux distribution in Europe, and the 1998 Linux Journal Readers' Choice for “Best Distribution”, it has not been particularly successful in the U.S. The reason for this is not clear (perhaps someone in marketing knows), but if word gets out about this distribution, the situation is likely to change.
Yet another Setup Tool is SuSE's software for installation, de-installation and maintenance. Once a system is installed, YaST stays around to help with many configuration tasks, and updates system files accordingly. (For example, if you want to change networking configuration, YaST asks what changes you want and automatically updates all files.) YaST is also the tool that installs the whole system in the first place.
Installation of SuSE is quite easy and extremely flexible, although not entirely automated—SuSE begins with a default (base) package and allows you to modify package selection to suit your needs. You can also load a few pre-configured selections (with the usual server, workstation, and complete installation options), though one ought to customize even these configurations. It is easiest just to have three or four pre-configured installations (as with Caldera), but SuSE probably has a number of reasons for taking the custom installation approach. For one thing, SuSE is more complete than most other distributions (five CD-ROMs is a lot of software, and the new 6.2 apparently has six) and customization makes more sense when dealing with so much software. Also, SuSE does not aim to be “Linux for Idiots” and would lose much of its flexibility were it dumbed down for people who can't decide what software they want.
One benefit of SuSE's devotion to custom installation is that SuSE has developed a system which incorporates many packages into the menuing system of KDE. In addition, YaST knows what dependencies the packages (numbering about 1000 for 6.1 and 1300 for the brand-new 6.2) have, and can automatically install these dependencies. YaST keeps track of redundancies to warn a user against installing software packages that are too similar or would be unused. Also, YaST has good descriptions of the software packages, so you always know what you're going to get (well, except for the occasional !! HIER FEHLT DAS LABEL !!). In these areas, SuSE is unique. For example, Red Hat offers far fewer packages and mostly does not incorporate selected programs into menuing systems. Caldera also offers fewer packages, and while it effectively incorporates programs into KDE, it offers four installation packages and no custom option. However, Caldera's installation program, Lizard, is probably the easiest.
Installation can take place in over a dozen languages (English is second on this list). Before installation begins, you have to load any special drivers you might need. Secretly, I wish SuSE would autoprobe, and in fact there is an automatic detection for necessary modules which actually works, but you have to find it first. Once the modules are taken care of, proper installation can begin.
Ultimately, installation is straightforward and easy to navigate, but, like Red Hat, often requires you to know what hardware you have. I would prefer more probing and perhaps more complete default installations (I had to select so many packages, it took a while), but there were no technical hang-ups, freezes or crashes. Manual configuration of networking was just like most distributions, and the system was booted and on-line fairly quickly.
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
